  commit 56aa2394b46b900a46fc068c6b39f6cfdb0933dc
  Author: Julien Grall <julien.grall@arm.com>
  Date:   Mon Apr 29 15:05:16 2019 +0100
  
      xen/arm: Add an isb() before reading CNTPCT_EL0 to prevent re-ordering
      
      Per D8.2.1 in ARM DDI 0487C.a, "a read to CNTPCT_EL0 can occur
      speculatively and out of order relative to other instructions executed
      on the same PE."
      
      Add an instruction barrier to get accurate number of cycles when
      requested in get_cycles(). For the other users of CNPCT_EL0, replace by
      a call to get_cycles().
      
      This is part of XSA-295.
